1.Ukuminyana kokubhoboza
Yinombolo yokubhobozwa imitha ngayinye yobude. Ngaphansi kwezimo ezijwayelekile, ukuthola umthamo omkhulu wokukhiqiza kudinga ukuminyana okuphezulu kwe-perforation, kepha ekukhetheni ukuminyana kwe-perforation, akunamkhawulo wokwandisa ukuminyana, kufanele kubhekwe lezi zici ezilandelayo:
Ukuminyana kwezimbobo ezinkulu kungabangela kalula ukulimala kwebhokisi.
Ubuningi bembobo bukhulu kakhulu, izindleko ziphezulu;
Ukuminyana kwezimbobo okweqile kuzophazamisa ukusebenza kwesikhathi esizayo.
Lapho ukuminyana kwezimbotshana kuncane kakhulu, ukwanda kokukhiqiza kubonakala lapho ukuminyana kwembobo kuyanda. Kodwa lapho ukuminyana kwembobo kukhuphukela enanini elithile, umphumela wokuminyana kwezimbobo esilinganisweni sokukhiqiza awubonakali. Okuhlangenwe nakho kubonisa ukuthi uma ukuminyana kwembobo kuyizimbobo ezingu-26~39/m, umthamo wokukhiqiza uzokhuliswa ngezindleko eziphansi kakhulu.
2. Ububanzi bembobo
Ipharamitha ebalulekile ekhombisa usayizi wokubhoboza. Usayizi wokubhoboza ngokuvamile uba ku-5 kuya ku-31mm (0.2 kuya ku-1.23in), kuye ngohlobo lokubhoboza kanye nenani lenkokhelo. Ngenani elifanayo lezinhlamvu, indawo yokubhoboza yokubhoboza okujulile incane, futhi leyo yokumboza imbobo enkulu inkulu. Uma sikhulu inani lezinhlamvu, likhulu imbobo yokubhoboza.
Esinye isici esithinta imbobo ukuvuleka phakathi kwesibhamu esibhobozayo ne-casing. Umphumela wokubhoboza ungcono kakhulu uma isibhamu esibhobozayo siphakathi nendawo yomthombo. Emsebenzini wokubhoboza, kuyadingeka ukuthatha izinyathelo ezifanele ukugcina isibhamu se-perforating phakathi nendawo yomthombo.
3. Isigaba
I-engeli ephakathi kwezimbobo ezimbili eziseduze ibizwa ngokuthi i-Angle yesigaba. Isigaba siphinde sibe nomthelela omkhulu ekukhiqizeni. Njengamanje, kunezigaba eziyisithupha ezivame ukusetshenziswa zokubhoboza okungu-0°, 45°, 60°, 90°, 120° kanye no-180°. Ekwakhekeni kwe-anisotropic, ukukhiqiza kukhula kakhulu lapho i-engeli yesigaba ishintsha ukusuka ku-180° ukuya ku-0° noma ku-90°, kodwa ukukhiqiza akushintshi kakhulu lapho i-engeli yesigaba ishintsha phakathi kuka-0° no-90°.
Inombolo enkulu yokuhlolwa kanye nokusetshenziswa kwensimu kubonisa ukuthi umthombo kawoyela unokukhiqiza okuphansi kakhulu lapho isigaba sembobo singu-0 °. Uma isigaba singu-120 ° no-180 °, umthamo wokukhiqiza uphakathi; Iphakeme kancane ngesigaba esingu-45°; Uma isigaba singu-60° no-90°, umthamo wokukhiqiza uphakeme kakhulu
4. Ukujula kokungena kokubhoboza
Isho ubude besiteshi sokubhoboza. Ukujula kokungena kokubhobozwa kunqunywa uhlobo lwesakhiwo seshaja yokubhoboza kanye nenani lezinhlamvu. Uhlobo lokungena okujulile lweshaja enkulu, ukujula kokungena kude, ukujula kokungena kuvamise ukuba kububanzi obungu-146~813mm, futhi ukujula kokungena kuyenyuka ngokwanda kwezinhlamvu. Isilinganiso sokukhiqiza sikawoyela Wells siyakhula ngokukhula kokujula kokubhobozwa, kodwa inkambiso yesilinganiso sokukhiqiza ikhula kancane kancane, okungukuthi, lapho ukujula kwembobo kukhuphukela kunani elithile, isilinganiso sokukhiqiza ngeke sikhuphuke kakhulu.
